The present invention relates to the preparation of optically resolved chiral compounds of β-amino acid type active pharmaceutical ingredients (API), more specifically to β-aminobutyryl substituted compounds and especially β-aminobutyryl compounds having γ-bound aryl groups. The present invention more particularly relates to the preparation of enantiomerically enriched chiral compounds useful as intermediates for the preparation of anti-diabetic agents, preferably sitagliptin.
